The invention is "shown applied to a ma- W chine of the type illustrated and described in Letters Patent of the United States No. 1,242,-

. 170 issued to'F. L. Fuller on October 9, 1917 and No. 1,619,796 issued to B. M. Shipley on March 1, 1927. The subiect matter of the present invention constitutes a division of applicationffor' Letters Patent of the United 'States,Serial No. 662,207 filed September 1923;by B, M. Shipley. l

i The object of thi invention is to provide 15 releasing mechanism whereby keys depressed in a plurality of banks may be released simultaneously by depressing the release key located in one of the banks of keys.

WVith this and incidental objects in view, the invention'consist-s of certain novel features of construction and combinations of parts, the essential elements of which areset forth in appended claims and a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form part of this specification. 2

V 4 General description I correct; The waiterbrings the order to the kitchen where itv is filled, and then returns with the food to the checker s desk. The i checker places the check, upon which the cus tomers order is written, in the register and depresses a key or keys representing the waiters number. These keys are so coir st-ructed that they will remain depressed until either another waiters key number is set up or until they are released by depressing the release key. It is, therefore, necessary to depress the waiters key on the entry of the first item only of the order. The prices of p the various items of the order are then entered into the register and printedon the check opposite the items.

The machine is provided with indicators, printing mechanism and totalizers, none of which are shown herein, as they form no part of this invention and reference to applicants copending application, Serial Number 662,- 207, filed September 12, 1923 is suggested for anunderstanding of the complete machine.

Key?) card The keys of each of the three banks" of waiters keys are slidably mounted in a key frame 26 (Fig. 2) supported by two rods 27 and 28 carried by two machine side frames in a manner well known in the art. The keys 25 have shoulders 29 formedthereon, adapted' to cooperate with pins 30 carried by a detent 31, supported byarms 32 and 33, pivoted to the key frame 26. When one of the waiters keys, 25 is depressed, the beveled edge'of the shoulder 29 will movethe detent 31 downwardly until'the shoulder on the'key has passed the pin 30, whereupon the detent will be returned to its normal position by a spring, to be later described, and will thereby hold the key in its depressed position. A locking bar 34 (Fig. 4) is also provided for the purpose of locking the depressed keys in their depressed positions and the undepressed keys in their normal postions during the operation of the machine. In Fig. 4 the locking bar is shown in its normal position. At its upper end this locking bar is pivoted on an arm 35 which has a slot cut the-rein cooperating with a pin 37 carried by an arm 38 fast on a shaft 39, which is the well known release shaft provided in machines of this type. T release machines of this type for operation the release shaft 39 is given a rocking movement in counter-clockwisedirection, as viewed in Figs. 2 and 4 by mechanism old and well known in the art, and which is fully illustrated and described in the above mentioned patents and the above mentioned application.

The counter-clockwise movement of the shaft- 39 through the slot and pin connection just described, will rock the arm clockwise and move the locking bar 34 upwardly to position one of a plurality of hooks 40, carried thereby, which corresponds with the key depressed, in engagement with a pin 41, carried by said key, and thereby lock the key in its depressed position. The hooks 40 corresponding to the undepressed keys will be moved beneath the pins 41 for these keys, and thereby prevent any of the undepressed keys from being depressed until the mecha nism is again in its home position.

Mechanism is provided whereby it is necessary to depress one or more of the waiters keys before the machine can be released for operation. Fast on the release shaft 39 is an arm 42 (Fig. 2) having a lip 43 so formed as to normally contact a pin 45 carried by an arm 46, fast on a yoke 47 loosely mounted on a shaft 48 supported by the machine side frames. The arm 32 which carries the upper end of the detent 31, previously mentioned, has an extension carrying a pin 49 which is adapted to cooperate with an arm 50 also fast on the yoke 47 (Figs. 1 and 2). It can be seen from Fig. 1 that each bank of waiters keys is provided with one of the arms 50. It is evident from Fig. 2 that so long as the pin 45 lies in the path of the lip 43 of the arm 42, it is impossible to release the machine as the release shaft 39 cannot be rocked in counterclockwise direction. If, however, a key in any of the banks of waiters keys is depressed, the pin 49, through its engagement with the arm 50, rocks this arm, the yoke 47, and arm 46 clockwise far enough to remove the pin 45 from the path of the lip 43 to permit the arm 42 and the releasing shaft 39 to rock counter-clockwise to release the machine.

No means is provided for releasing the waiters keys at the end of an operation, and it is desirable to have them remain in their depressed positions until all of the items which constitute a guests order have been entered by the checker. When another waiter presents his order to be checked, the checker need only depress the keys corresponding to the new waiters number and the key or keys corresponding to the number of the previous waiter will be automatically released. This release feature is old and well known in the art and means for accomplishing this shown in Fig. 2. It is evident that when any key in the waiters bank is depressed, the de tent 31 is moved downwardly, as previously described and any key which may have been previously depressed will be released as soon as the pin 30 on the detent 31 is removed from the shoulder 29 on the key and the key will, therefore be returned to its normal un-,

depressed position by a spring not shown.

If for any reason it is desired to release depressed waiters keys without depressing other waiters keys, a release key 51 (Figs. 2, 3, and 4) may be depressed. This release key is located in the 9 position of the left Y hand bank of waiters keys. It carries a pin 52 which cooperates with a cam edge 53 formed on a releasing bar 54 pivotally carried by arms 55 and 56 supported by the key frame for this bank. The releasing bar 54 has at its lower end a foot 57 which normally lies just above one end of a rod 58 carried by two arms 59 of a yoke 60 loose on a shaft 61 supported in the machine side frames. The rod 58 cooperates with projections 62 of zero stop pawls 63, one for each of the banks of waiters keys. These pawls 63 are pivotally mounted on the key frames 26 for their respective banks and carry pins 64, embraced by the bifurcated ends 65 of the arms 33 which support the lower ends of the detents 31 for the banks of waiters keys, as above mentioned.

From the above description it can be seen that when the release key 51 is depressed, the releasing bar 54 will be moved downwardly, and, due to the engagement of the foot 57 with the rod 58, the arms 59 and yoke 60 will be rocked counter-clockwise about the shaft 61. This movement of the rod 58 will rock the zero stop pawls 63clockwise, and due to the slot and pin connections between the pawls 63 and their corresponding arms 33, will rock the arms counter-clockwise and thereby lower the detents 31 sufficiently to release any keys which may have been depressed. The zero stop pawls 63 are nor mally held in positions shown in Fig. 2 by means of springs 66 extending between pins on projections 62 of the pawls, and pins carried by the key frames 26.

While the forms of mechanisms herein shown and described are admirably ada ted to fulfill the objects primarily stated, it s'to 1. In a machine of the class described, the

combination of a plurality of banks of keys, a plurality of detents one associated with each bank of keys, and adapted to cooperate witht he keys and hold said keys, when de-.

pressed, in their depressed positions, pawls operat'ively connected to said detents, and

adapted to be moved thereby, a rod common to all of said pawls, a release key in one of said banks of keys, and a releasing bar operated by said release key to actuate said rod and release all of said first mentioned keys.

2. In a machine of the class described, the combination of a plurality of banks of manipulative keys, detents cooperating therewith to hold said keys, when depressed, in depressed positions, zero stop pawls operatively connected to said detents, and adapted to be moved to their ineflective positions by their respective detents upon depression of one of the associated keys in each bank, a rod conimon to all of said zero stop pawls, a special key substituted for the highest order key in the highest order bank, and a releasing bar cooperating with the special key, and adapted upon depression of said special key to move saider od thereby moving all of said zero stop pawls and releasing all of said keys.
